Apple’s investment in the mining company MP Materials will also help the tech giant reduce its dependence on China for rare earth metals.

MP Materials will supply Apple with magnets it produces at a Texas facility, expanding Apple’s U.S. supply chain at a time when President Trump has pressured Apple to do so.

The moves by Apple and the Pentagon are part of a broader U.S. push to nearshore rare earth supply chains. Earlier this year, President Trump proposed annexing Greenland, an autonomous Danish territory estimated to contain $4.4 trillion worth of rare earth reserves. Vice President JD Vance made a surprise visit in support of the plan.
